This is through Querying the position of the synchronization angle mark to be checked realized in the cylinder segment. Will a location identified from several possible, then this location, defined by an upper and a lower limit, in Data record that is stored in the computer of the control unit Assigned cylinder. If a cylinder is identified, it runs then a cylinder counter.
  • This cylinder counter is running in a four-cylinder internal combustion engine from zero to three. In general, Z cylinders are counted up to Z-1. By checking the correctness of this process can be further information regarding the functionality of the System. To determine whether the process is correct is, the position of the Synchronization angle marks checked. The determined Meter reading indicates a specific location of the Synchronization angle mark, which is stored in the data record is. If the angle mark that occurs has this target position, classified them as plausible. Is it in a position other than that determined by the cylinder counter and with a lower and upper limit position defined in the data set, the relevant synchronization angle mark is used as classified incorrectly and possibly a malfunction of the system recognized and displayed.
